 ## After component render (`OnAfterRender{Async}`)

+
+<xref:Microsoft.AspNetCore.Components.ComponentBase.OnAfterRender%2A> and <xref:Microsoft.AspNetCore.Components.ComponentBase.OnAfterRenderAsync%2A> are invoked after a component has rendered interactively and the UI has finished updating (for example, after elements are added to the browser DOM). Element and component references are populated at this point. Use this stage to perform additional initialization steps with the rendered content, such as JS interop calls that interact with the rendered DOM elements.
+
+These methods aren't invoked during prerendering or server-side rendering (SSR) because those processes aren't attached to a live browser DOM and are already complete before the DOM is updated.
+
+For <xref:Microsoft.AspNetCore.Components.ComponentBase.OnAfterRenderAsync%2A>, the component doesn't automatically rerender after the completion of any returned `Task` to avoid an infinite render loop.
